Carotenoids form one of the most important classes plant pigments and play a crucial role in defining quality parameters fruit vegetables. Their is to act as accessory for light harvesting prevention photo-oxidative damage, well acting attractants pollinators. function antioxidants shows interesting parallels with their potential foods humans. are products isoprenoid biosynthetic pathway. The enzymes leading carotenoid biosynthesis have all been characterised, more recently genes encoding...

A food frequency questionnaire (FFQ) and carotenoid database with information on α - β-carotene, lutein, lycopene β-cryptoxanthin was prepared used to compare the intakes in five European countries: UK, Republic of Ireland, Spain, France The Netherlands. Eighty, age- (25–45 years) sex-matched volunteers were recruited each countries. FFQ most commonly consumed rich foods participating countries calculate intake carotenoid-rich foods. median total based sum carotenoids, significantly higher...

High intakes of fruits and vegetables, or high circulating levels their biomarkers (carotenoids, vitamins C E), have been associated with a relatively low incidence cardiovascular disease, cataract cancer. Exposure to fruit vegetable diet increases antioxidant concentrations in blood body tissues, potentially protects against oxidative damage cells tissues. This paper describes carotenoids, tocopherols, ascorbic acid retinol well-defined groups healthy, non-smokers, aged 25–45 years, 175 men...

Carotenoids are thought to act as antioxidants in vivo, decreasing oxidative damage biomolecules and thus protecting against coronary heart disease cancer. However, human intervention studies with beta-carotene have given equivocal results terms of cancer incidence. In an alternative molecular epidemiological approach, we employed the 'comet assay' (single cell alkaline gel electrophoresis) measure strand breaks, oxidized pyrimidines altered purines DNA lymphocytes from volunteers...

To establish reference ranges for use in clinical and epidemiological studies, we determined concentrations of retinol, alpha-tocopherol, beta-carotene, alpha-carotene, beta-cryptoxanthin, lutein, zeaxanthin, lycopene 450 Spanish control subjects 123 patients with insulin-dependent diabetes mellitus (IDDM). Results were grouped according to sex, samples collected throughout the year. Concentrations retinol significantly lower beta-carotene alpha-carotene higher women than men, both controls...

The 'antioxidant hypothesis' proposes that vitamin C, E, carotenoids, and other antioxidants occurring in fruit vegetables afford protection against heart disease cancer by preventing oxidative damage to lipids DNA, respectively. To test elements of this hypothesis, we have measured blood levels dietary antioxidants, 8-oxodeoxyguanosine (8-oxo-dG) concentrations lymphocyte healthy men women from five European countries: France, Ireland, Netherlands, Spain, the U.K. Volunteers, aged 25–45,...

Abstract Lutein, a non‐provitamin A xanthophyll, is widely distributed in fruits and vegetables frequently consumed. In human serum, lutein transported by lipoproteins selectively accumulated certain tissues (eg the retina). Epidemiological studies suggest that high intake serum levels of are associated with lower risk cataracts age‐related maculopathy. Subjects diagnosed (CA; n = 5) or macular degeneration (ARMD; agreed to take three capsules per week. Each capsule potentially provided...

To compare the in vitro bioaccessibility of lutein, zeaxanthin, β-cryptoxanthin, lycopene, and α-and β-carotenes from relevant dietary contributors, a gastrointestinal model was used to assess stability, isomerization, carotenol ester hydrolysis, micellarization. Salivar, gastric, duodenal, micellar phases were extracted, with without saponification, analyzed by using quality-controlled HPLC method. The stability carotenoids under digestion conditions >75%, regardless food analyzed, whereas...

The fishing sector produces large amounts of waste in fish markets and processing industries. These by-products are mainly used the manufacture meal. However, there other potentially valuable uses. One low-investment possibility is elaboration agricultural products by composting remains with marine materials such as seaweed. main purpose this work was to obtain a fertilizer suitable for use organic agriculture, mix seaweed waste.
